Thank You very mutch . but i have 1 more question .
What i need to do , if i dont have Packages folder?
I have just those : Connectivity Cable Driver , Envira , Nokia Software Recovery Tool , Nokia Software Updater for Retail and Nokia Suite

I ended up pulling the Windows 8.1 Update 1 ROM from the nokia servers and using the Nokia Care Suite to recover. I kept getting the developer preview errors about the install partition being full when trying to install. It took a few hours and re-entering passwords several times, but I'm relatively happy with the outcome.

XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality.Are you a developer?
